3 1. General 1.1 Scope of this Manual This Operating Manual applies to a H(T)SG Globoidal Cam Indexing Gear Unit Anyone at the user's premises who sets up, puts into service, operates, maintains or repairs this Indexer must read the Operating Manual and observe its instructions. Keep this Operating Manual for reference at a safe and easily accessible location. Make sure that you are familiar with the safety instructions first. In this manual, the Cylindrical Cam Indexing Gear Unit is referred to as Indexer. Each Indexer is designed and built according to the state-of-the-art and complies with generally accepted safety rules. The Indexers are designed exclusively for indexed movements of a payload that does not endanger people, equipment or the environment while moving. These Indexers must only be used within the scope of this Operating Manual or according to the specifications agreed to in the sales documents. Any other use or any use exceeding these specifications, such as higher rotational speeds and/or higher loads or other mounting positions, do not comply with the Indexers' intended use. The manufacturer cannot be held liable for any damage resulting from such a use. This risk is born solely by the user. Intended use includes reading the operating and maintenance instructions and complying with the servicing and maintenance requirements. Only qualified professionals who understand the functionality of the Indexers are permitted to carry out maintenance work. BWV_H(T)SG_E 3 / 20

4 1.2 Safety Notes Before putting the Indexer into service, read the operating and maintenance instructions carefully. The Indexer complies with generally accepted safety rules. When installing the Indexer into a machine or plant, machine or plant attachments such as levers, toothed gear wheels with chains or similar can cause severe injuries to or death of the user or bystanders. Indexers must not be put into service, if the machine or plant in its entirety does not comply with the machine directive 2006/42/EC. Output shaft or flange with high torque! Do not reach into the operating range of the output shaft and its attachments! Crushing hazard by attachments mounted on the output shaft. Do not reach into the operating range of the output shaft and its attachments! For such a case, the user must implement all necessary protective measures on site. To protect operators from injuries that can be caused by the Indexer, install protective grating, covers or light curtains suitably. Always adhere to the relevant regulations for prevention of accidents as well as generally accepted health and safety regulations. Improper modifications and the use of replacement parts and additional equipment not recommended by the manufacturer can result in injuries to personnel or damage to property. Before starting any maintenance work, make sure that the Indexer is locked out and cannot be started. Any work on the Indexer requires specific technical knowledge. Preferably have HEINZ technicians or specifically trained professionals carry out this work. You cannot turn Indexers manually into one of their end positions. If position indexing is required, carry out this action by moving the input shaft only. BWV_H(T)SG_E 4 / 20

5 The Indexers are designed exclusively for indexing a payload that cannot endanger persons, equipment or the environment while moving. The Indexers must only be used within the scope of this Operating Manual and according to the specifications agreed to within the sales documents. Any other use or any use exceeding these specifications does not comply with the Indexers' intended use and voids any warranty by the manufacturer. When the Indexer is completed with an electric motor, this motor must be protected against overload. Before putting the Indexer into service, always replace the plug at the oil inlet with a vent plug. 1.3 Shipping Each Indexer is checked thoroughly and packaged properly before shipment. After unpacking the Indexer upon receipt at its destination, please inspect the Indexer for any damage sustained during transport. Should you note discrepancies, please report these to the carrier immediately. 1.4 Transport Instructions To move the Indexers, only use handling equipment approved to carry their weight. For weight specifications, refer to section 1.5. We have provided mounting holes for lifting screws. Attach suspension ropes or chains only to these lifting screws. To determine the weight of Indexers, refer to section 1.5 and the respective Indexer-type tables. BWV_H(T)SG_E 5 / 20

7 2. Information on the Use of the Indexers 2.1 Mounting Position The universal design of these Indexers allows for virtually any mounting position on a machine or plant. When ordering an Indexer, please state mounting position, location of mounting holes and, if necessary, location of oil holes. The specified mounting position is crucial for proper lubrication of the Indexer components. Do not change this position in the machine or plant. 2.2 Indexer Installation The output shaft or flange and the input shaft are subjected to variable torques as a result of the Indexer's working principle. Therefore: - Always install the Indexers on a stable machined base. - Always secure the mounting bolts and fix the assembly additionally with dowel pins, if possible. - Always connect the Indexer to the driven payload directly, backlash-free and torsionally rigid. This also applies to the Indexer input shaft. 2.3 Indexer Operation When operating the Indexer, always observe the following instructions: Elasticity and play in the driven masses can result in vibration excitation and must be avoided. Any overload protection should be mounted to the output flange, if possible. BWV_H(T)SG_E 7 / 20

8 3. Putting into Service 3.1 How the Indexer Works The Indexer is a compact, robust unit that uses exactly calculated cams to transform a constant input speed into a predefined optimum output movement that is smooth and intermittent. The cam rollers running in the cam followers are precision guided along the cam by the hardened and polished cam track. This cam track has various leads and is divided into a dwell angle range and an indexing angle range. When rotating the cam, the cam track and the cam rollers generate a predefined smooth movement of the output shaft. As the cam is usually shaped symmetrically, rotations to the left and to the right are equally possible. The dwell angle range has a lead of zero. This causes a precisely defined self-locking positioning of the output shaft through the cam rollers without an additional locking device. When using a brake motor, the exact positioning of the output shaft is determined by the position of the cam rollers in the dwell angle range and not by the motor braking accuracy. The full dwell angle range is available for braking (refer to 3.3). 3.2 Oil Level Before putting the Indexer into service, always check the oil level. The oil level is sufficient if oil is visible in the sight glass. The following table lists the average filling quantity. Basic series Gear type An insufficient oil level adversely affects the functioning and service life of the Indexers. Oil qty. [ L ] modified series Gear type Oil qty. [ L ] Gear type Oil qty.

9 3.3 Intermittent Service If the dwell angle range of the cam is not sufficient for a production-related standstill, you can extend the hold time using a brake motor. Braking is triggered by a limit switch activated by a cam connected to the input shaft. When putting the Indexer into service and during operation, make sure that after a braking action, the keyway of the input shaft always points to the casing side 6 and to the rotary axis of the output flange. In case of double indexing, this position can also be shifted by 180. The cam rollers must be in the middle of the dwell angle range of the respective cam. For Indexers with an additional index hand, this index hand must be within the middle range of the marking label after braking. 3.4 Important Information For input drives with two rotational speeds, normal operation is always at the higher speed (fast traverse speed). Only use the lower speed (creep speed) for setting up equipment or following an Emergency Stop to return to the dwell angle range.. Do not activate creep speed for automatic operation while in the movement phase. For controls that only enable switching to fast traverse speed via creep speed, this switch must take place within the dwell angle range, i.e. only within the marking label range or when the output shaft is at standstill. If these warnings are disregarded, any damage caused will not be covered by the warranty of the manufacturer. BWV_H(T)SG_E 9 / 20

12 5. Information on Preventative Maintenance 5.1 Preventative Maintenance Schedule To ensure mechanical reliability, we recommend the following checks at regular intervals but at least every 8000 hours of operation: 1. Check oil level and top-up as necessary 2. Check casing and bearing covers for overheating, discolouring and unusual noises. 3. Check Indexer for overheating, unusual noises, functional reliability and play. 4. Check functional reliability of all seals Do the following, if the condition of the items described does not correspond to their original state any longer: 1. Top-up lubricant (refer to sections 3.2 and 4.4) 2. Replace roller bearing at input and output shaft (refer to section 6.2) 3. Replace cam rollers (refer to section 6.2) 4. Replace seals (refer to section 6.2) After approximately 30,000 hours of operation, we recommend that you replace all roller bearings and cam rollers. At the same time, also replace all seals to avoid any damage to the Indexer caused by a possible loss of lubricant. BWV_H(T)SG_E 12 / 20

13 6. Replacement Parts Assembly Before starting any disassembly works, carefully read the entire text. Always clean and check all components for perfect condition before installing them. For disassembly and reassembly of component parts, refer to the replacement parts list. When using solvents, make sure that they do not get into contact with O-rings or sealing rings of the shafts. In case of queries or when ordering replacement parts, please have type number and serial number ready for faster processing. Any repair work requires specific technical knowledge. Preferably have technicians of HEINZ AUTOMATIONS-SYSTEME GmbH carry out this work. 6.1 Tapered Roller Bearings / Deep Groove Ball Bearings When installing tapered roller bearings and deep groove ball bearings, make sure to adjust the bearings free from backlash. You can correct a bearing clearance, which is too large or too small, by adapting the bearing cover or the eccentric cover. Then check the unit for smooth running by turning the input shaft. Readjust, if necessary. BWV_H(T)SG_E 13 / 20

14 6.2 Globoidal mechanism The mechanism is a unit consisting of globoidal cam, cam followers and turret.
